V 'lhepresent invention relates to an attachahlesafetylocking device "for-use in slug and type-casting machines to prevent breaking and'demaging of moldliners b the ejector vents" damagin and breakin of mold liners bythe ejector blade While the cams are rot tatihg.

To the aboveand other ends, whie'hivillbe 1 fonndfas the description proceeds, this in vention resides in the arrangements of a coinbinatron' of parts and in the details of ll/SCOU- stmetien; hereinaftendescribed= and claimed.

The form of this invention is illustrated in the accompanying drawings, in which Fig. 1

There is a i long which engages a starting clutcln'locatedfon the main cares of said slugand type-casting -machine. The said cams'arc cz'vused to rotate Whensaid starting clutch is engagedbysaid starting roller, as the upper end ofth'e lohg finger is moved by fingei' Q, of the transfer slide which slides the matrices through the intermediate channel.

An ex tension pivot pin .23 is adapted to support said adapter slide block 31 and springs 29 and 35 (Fig. 2).

The timing block 28 is held in position by screw 27 located at lug Y of supporting collar :22 (Fig. 2), having an aperture through which the said reciprocal register rod e):- tends being adjustable to release said intermediate transfer blade at N (Fig. 2), by means of a compression spring 33 in the lower portion of said aperture and the adjusting'screw 30 in head of said timing block.

Means are provided for holding the safety locking arrangement inoperative when casting folios or whenever desired. This holding means has as a part a member provided with a hook 18 and which is attached to the justification lever 5 at 0. Plate 19 has perforations to adjustably receive hook l8 and a latch for attachment to frame T of the type casting machine. The adjustment provided between plate 19 and hook 1S adapts the holding means to various models of typecasting machines.

The unlocking arrangements comprise a dial lever key 6 which is adj ustablc at 9 (Fig. 1) adapting it for use on various models. An interchangeable transfer blade 14 being slotted at K accommodating a channel latch screw 7 which enables it to be drawn downward by said dial lever key 6 which is also operatively connected with said dial lever I which controls and changes the size of ejector blades, its lug D (Fig. 1) being engaged by dial lever key 6 when registering multiple 4 at I (Fig. 2).

This invention constitutes a positive and practical mold liner safety arrangement, automatic throughout. The operator may operate this device by raising the dial lever upward to size 4 then downward to the size of blade wanted. This should be done before the ope 'ator sends in his first line of matrices for each change of mold or mold liner made.

Having thus described the invention I claim:

1. In an automatic liner safety device, adapted to be attached to the lower side of the intermediate channel, the vise locking screws, the mold turning pinion and the dial lever, supporting brackets for end and front adapted to support a section of the device attachable to the intermediate channel, a channel latch located at the entrance of the intermediate channel and movable into and out of the path of the leading delivery slide finger, an interchangeable dial lever key adapted to engage a lug on an interchangeable transfer blade, an interchangeable transfer blade adapted to withdraw a channel latch, a neutralizer link operatively connected with a carriage frame and the justification lever adapted to hold the said. locking ar- 'angements in neutral when desired, a justilication lever movable into and out of the path of the trimming knife sector cover or block adapted to withdraw an outside transfer blade. an outside transfer blade operatively connected with the justification lever and also adapted to move the channel latch to obstructing position when the vise is opened and to move out of engagement with the channel latch when the justification lever is engaged by the sector cover or trinunin; knife block in normal locked position of the vise frame, a hood operatively connected with the justili 'ation lever and the outside transfer blade also adapted to hold the channel latch in perpendicular position.

2. In an automatic liner safety device, adapted to be attached to the lower side of the intermediate channel, the vise locking screws, the mold turning pinion and the dial lever, supporting collars attachable to the vise locking screws adapted to support a ti ming block mechanism, an intermediate transfer blade operatively connected with a reciprocal register rod and a mold turning pinion also adapted to move the channel latch to obstructing position when the mold turning pinion is revolved with the hand and to move out of engagement with the channel latch when the mold turning pinion is re-seated in normal position by allowing the reciprocal register rod to release it, a reciprocal register rod operatively connected with the adapter slide block and the intermediate transfer blade adapted to engage the said intermediate transfer blade when the mold turning pinion is moved outward to be revolved by hand and to move out of engagement with the said in termediate transfer blade when said mold turning pinion is released or re-seated in normal position, a timing block operatively connected with a supporting collar and the reciprocal register rod adapted to time and control the movement of said reciprocal register rod, an adapter slide block operatively connected with the reciprocal register rod and the mold turning pinion adapted to move the reciprocal register rod with each outward movementof the mold turning pinion, and means of adjusting said adapter slide block; an extension pivot pin operatively connected with the mold turning pinion and the adaptor slide block adapted to support the said adapter slide block mechanism.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature.
